Hermit Thrush
Catharus guttatus
Summary 4
The hermit thrush (Catharus guttatus) is a medium-sized North American thrush. It is not very closely related to the other North American migrant species of Catharus, but rather to the Mexican russet nightingale-thrush.
Description 5
This species measures 15 to 18 cm (5.9 to 7.1 in) in length, spans 25 to 30 cm (9.8 to 11.8 in) across the wings and weighs 18 to 37 g (0.63 to 1.31 oz). Among standard measurements, the wing chord is 7.8 to 11.1 cm (3.1 to 4.4 in), the bill is 1.6 to 1.9 cm (0.63 to 0.75 in) and the tarsus is 2.7 to 3.3 cm (1.1 to 1.3 in). It is more compact and stockier than other North American Catharus thrushes, with relatively longer wings. The hermit thrush has the white-dark-white underwing pattern characteristic of Catharus thrushes. Adults are mainly brown on the upperparts, with reddish tails. The underparts are white with dark spots on the breast and grey or brownish flanks. They have pink legs and a white eye ring. Birds in the east are more olive-brown on the upperparts; western birds are more grey-brown.
Behaviour 5
Hermit thrushes breed in coniferous or mixed woods across Canada, southern Alaska, and the northeastern and western United States. They make a cup nest on the ground or relatively low in a tree.
While most hermit thrushes migrate to wintering grounds in the southern United States and south to Central America, some remain in northern coastal US states and southern Ontario. They usually breed in forests, but will sometimes winter in parks and wooded suburban neighbourhoods.
They are very rare vagrants to western Europe and northeast Asia.
They forage on the forest floor, also in trees or shrubs, mainly eating insects and berries.
